Works great to replace the defective original rheostats in my Cessna 150L. Something worth noting -- the slightest bit of panel modification was needed to make them fit in the original space (about 20 seconds with a dremel and done).
Another MAXDIM product for me. I used the DUODIM for dash lights and overhead but do not like dash lights and EI gauges controlled by same line. So I purchased this singe dimmer and it is controlling ALL my EI gauges. This way I have more control over lighting intensities, dash vs EI.

This dimmer is solid state.
Per the MFG. - they are PWM and have passed the DO-160 (EMI noise) testing required by the FAA.
Yes this dimmer can be used on both. Plug and play.
Some Garmin units have internal PWM (Pulse Width Modulation) dimming circuits. If these units have internal PWM dimming and it cannot disabled, you should not hook it up to our dimmer. It is not good practice to use one PWM dimmer to dim another unit using its own PWM dimming. If the Garmin unit does not have internal PWM dimming or if it does but the internal PWM dimming can be disabled, then the unit should work fine with our dimmer.
We always recommend confirming in the Garmin manual before installing or trying any subcomponent.
